Astronomical Papers. Volume XXII. Part II. A Discussion of the Observations of Neptune.

摘要

The Royal Observatory at the Cape of Good Hope obtained a very long series of observations of Neptune with their heliometer. The positions of the reference stars in this series have been transferred to the system of FK3 and new residuals computed with respect to the ephemeris positions available at the time of observation. Differences between the ephemeris used by the Cape and that adopted by this investigation were computed and applied to the heliometer observations. Residuals with respect to both ephemerides are exhibited in the appropriately labeled table.
